Application filed March 28, 1913. Serial No. 757,291.

To all whom, it may concern Be it known that we, JOHN W. ROBERTS and ARTHUR P. BREWSTER, citizens of the United States, and BOYD BRYsoN, subject of the King of England, respectively, residing at Passaic, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Sewing- Machine Installations; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to. the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification This invention relates to a structure for mounting machines in a series, and is designed particularly for manufacturing plants in which machines, such as sewing machines, are operated by power and large quantities of material are run continuously through the machines.

The invention is further designed to provide an installation in which the machines are so mounted that even when in a series they are easily accessible on all sides and are driven by a common driving means, as the pulley ends of the machines are above the support and are in line and also in line with the driving means.

The invention further provides a support or table which leaves the table under the sewing mechanism free so that boxes with the rolls or bolts of cloth or other material to be sewed can be removed, installed and moved about without hindrance, and that part of the sewing mechanism under the table is accessible.

The invention also has for its object the easy feeding of material to the machines, the tablets on which the machines are mounted being inclined to bring the front of the tablets lower than the back.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a top view of an installation according to our present invention. Fig. 2 is a side view of the installation shown in Fig. 1, and Fig. 3 is an enlarged section be understood that the installation is adaptuprights 10 which are arranged in two lines and support the stringers 11, the stringers beng arranged longitudinally and being shown in Figs. 1 and 2 as being long enough to support six sewing machines, but in the larger plants the stringers are run for a much longer distance so that a large number of machines are arranged on the same support. Supported on the stringers 11, and transversely arranged thereon, are the tablets 12, the tablets projecting from alternate sides of the support, the tablets being preferably arranged to rest on both stringers, but to project from one only. There are many Ways in which the tablets might be arranged on the supports, but the preferred way is to arrange them in pairs, the pairs being separated from each other, but the two tablets making up the pairs are arranged close together, this arrangement be ing shown more particularly in Figs. 1 and 2 Each tablet supports a machine 13, the machines being arranged with a stitching mechanism projecting outward from the support and their pulleys or similar driving mechanism extending over the support. The tablet beyond the sewing mechanism of the machine forms a guide or table for the goods sewed on the machine. The driving portion of each machine in the illustration consists of the pulley 14, these pulleys being arranged substantially in line, the machines projecting over the, support far enough to permit thisalinement. Each pulley 14 is driven by means of a belt 15, each belt 15 being in turn passed over a driving pulley 16, the driving pulleys 16 being mounted on a driving shaft 17 which driving shaft 17 runs longitudinally through the support between the uprights, being arranged in bearings 18 which serve to support and hold the shaft 17 in alinement. The shaft 17 is driven from any suitable source of power, the pulley 19 being shown in the drawing to provide for the driving of the shaft 17. Each tablet can be further strengthened by a bracket 20, the brackets being fastened to the uprights 10 and extending underneath the tablets.

In factories, where machines are run in series, the machine is provided with what in 'the opposite tablets of opposite pairs and between the stringers 11. This space 21 is thus adapted for use for two machines, there- I y economizing space and also power. In

the drawing we show but one form of ac cessory at the left of Figs. 1 and 2, illusbobbins and the like,

trating take-up rolls 22, showing these rolls in a very simple manner, the rolls being driven by gears 23 which in turn are driven by gears 24 on the secondary shaft 25 which is supplied with a pulley 26. A belt 27 passing over the pulley 26 and also over the shaft 17 serves to drive the secondary shaft 25.

It will be understood that suitable connecting and disconnecting means for both the machine and the secondary shaft and the accessories can be installed, and these are not shown in detail in this application. The installation as shown provides for a long narrow support which supports the machines and their tablets, the machines partly overlying the support and thetablets extending beyond in extension, thereby providing a free space underneath each tablet which makes the sewing mechanism underneath the tablet readily accessible, which is desirable for the purpose of installing or for observing the operation of the machine and for making repairs, the free space also being utilized for the installation, removal, and also for the moving about of boxes 28.

It is customary in plants where long strips of goods are worked, take for instance in handkerchief factories where the cloth is taken in rolls or bolts and fed to the machine, to provide boxes 28, placed under the tablets, for the goods. In the drawing we illustrate the box 28 with the goods 29 emerging therefrom and passing over a suitable guide 30, then passing through the machine to be stitched or hemmed, and then descending again as at 29 and being deposited in the box 28. When the goods have been run through in one direction, the box is, turned around and the end lately deposited in the box is fed through the machine with its other edge adjacent to the hemming or stitching mechanism so that the other end is operated upon by the machine. This installation provides for the moving of these boxes, and they can be turned around and shifted from machine to machine without'hindrance, since there is nothing tointerfere with the motion of the boxes 28. This is important in a plant, as it saves time and labor, and this mechanism in practical operation has been found to be desirable and very eflicient.

the tablets are fastened on the stringers they have the proper slant or inclination.

Having thus described our invention, what we claim is:

l. A sewing machine installation comprising a longitudinal support of spaced members, the space providing room for driving mechanism, tablets projecting alternately from opposite sides of the support at the top thereof, and sewing machines mounted on the tablets so as to receive and deliver goods from and into the spaces between tablets on the same side.

2. A sewing machine installation comprising a longitudinal support of spaced members, the space providing room for driving mechanism, tablets projecting alternately from opposite sides of the support at the top thereof, and sewing machines mounted on the tablets so as to receive and deliver goods from and into the spaces between tablets on the same side, the machines being also disposed so that they can be operatively connected with driving mechanism on the support.

3. A sewing machine frame consisting of parallel longitudinal stringers, uprights on which the stringers are mounted to form a support, and tablets arranged in pairs, each tablet of a pair extending across and secured to both stringers and projecting transversely from the side opposite the other tablet of the pair, the pairs being separated.

4 A sewing machine frame consisting of parallel longitudinal stringers, uprights on which the stringers are mounted to form a support, tablets arranged in pairs, each tablet of a pair extending across and secured to both stringers and projecting transversely from the the pair, the pairs being separated, bearings for a driving shaft arranged between the uprights, and sewing machines on the tablets and disposed so as to receive and deliver goods to and from the spaces between tablets on the same side.

5. A sewing machine installation comprising a longitudinal support, tablets arranged to project alternately from opposite sides of the support, and sewing machines arranged on the tablets with their ends that receive the power substantially above the support and with their sewing ends over the tablets, whereby the machines can readily receive side opposite the other tablet o f memos utilized for the reception of operating mechanism common to the take-up mechanism of 15 abutting pairs of tablets.

In testimony, that We claim the foregoing, we have hereunto set our hands this twentyfifth day of March, 1913.
